' Application filed Percmbcr'fil, [586 Serial 170.222.677. (No model.) a I To all whom, it may concern: v

Be it known that we, JUDsoN L. THOMSON and J ACOB J UNBEHnND,-of Syracuse, in the county of Onondaga, in the State ofNewYork, have invented new and useful Improvements in Itiveting-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear,v and exact descrip tion.

Our invention has for its object the production of amaehine fortheinsertion of rivets into the heels and toes of the soles of arcties and like overshoes in which the operation of inserting the rivet and clinching or heading the elinehingprongs shall be automatic and continuous by simply securing the overshoe upon a riveting-block and presenting the same to the punches and operating the clinching mechanism and feeding mechanism by the ac treadle; and to this end theinvention consists in a riveting-machine comprising an automatic feed for feeding the rivets to the heading mechanism, mechanism for distributing and arranging the. rivets circumfercntially on 2 the heel of the arctic or overshoe, and a cutoff for stopping thefeed automatically while the rivets are being clinched by the heading mechanism; also, in combining with the automatic feeding mechanism and combined adoj'nstable riveting-block ashoe holder; also, in providing a receptacle or hopper for the feed with discharge openings, and mechanism for.-

4 5 riveting-machine, illustrating the general con struction and arrangement of the parts. Fig. 2 is a front elevation from the top of the frame of the machine upward, illustrating the same in front elevation, showing the inserting device and the combined shoe-holder and riveting-block disengaged or in their normal position before the rivets are forced into the are tic. Fig. 3 is a like view showing the punches for inserting the rivets and the riveting-block and combined shoeholder raised in the position offorcing the rivets home into the arctic; Fig. 4 isa top plan illustrating moreparticu; larly the mechanism for operating the feeding hopper or receptacle and the lever for operating the plunger carrying the forcing- 6o punches and the spring for retracting the same. Fig. 5 isa side elevation of the machine similar to Fig. 1, showing, however, the treadle forced down and the riveting-punches and riveting-block up in the position for forc- ()5 ing the rivets into the arctic. Fig. 6 is an enlarged detached front view ofthe togglelevers and plunger for operating the combined riveting-block and shoe-holder. Fig.

Fig. 11 is a transverse section taken through the discharge-passageor slot in the bottom of the feed-receptacle or hopper, showing the contour thereof incrossscction. Fig.

12 is an enlarged detached view of the feedconveying tubes at their lower ends where they join with the exits or discharge-valves through which the rivets are forced into the arctic by the punches, and it also illustrates the mechanism forautomatically feeding the 'rivets one by one from the feed conveying tubes and the general constructionfandear- 5 ra-ngelnent of the parts in their connection with the frame of the machine. Fig..13 is an inverted bottom plan of thedischarge-valves and feed conveying-tubes and accessories,

showing in their arrangementhow the rivets Ice 1 are distributed eireumferentially on the toe or heel of an arctic or overshoe and inserted in one operation. Fig. 14 shows, respectively, an edge and side view of the cut-off mechanism for opening and closing the adjustable.

valves which are located at the exit of the feed conveying-tubes. Fig. 15 is an enlarged detached detail of the punches and dischargevalves, illustrating more particularly the construction and arrangement of the parts in relation to each other, and for this purpose the support for the ends of the discharge-valves is broken away in the figure. verse section of one of the discharge-valves, showing how the punch forces the rivet through the valve, and also the supporting-guide for for the punches and which support the spring down into the arctic.

discharge-valves at the ends of the feed conveying-tubes, andalso the pivoted guides for embracing the two sides of the spring-valves to accurately guide the rivet as it'is forced Fig. 18 is an enlarged detached view of the cut-off mechanism in the feed conveying-tubes for regulating the feed Fig. 19 is a detached detail of a modification, showing a single-feed conveying-tube machine for inserting rivets in the stay of an arctic or overshoe, and Fig. 20 shows the arrangement of the pivoted guide upon its support whereby the guide is swung off at the right time as the punch descends and forces the rivet into the arctic or overshoe.

A represents the feed receptacle or hopper, andthe same is made preferably circular in shape and of suflicient capacity-to holda large number of rivets. The hopper is provided with a hole, 1, for the shaft 2, and the shaft 2 carries the frame 4, from which depend brushes 3, which oscillate on the shaft 2 as a pivot and serve to feed the rivets to the discharge openings or passages 5. The bottom of the hopper or receptacle A is conical in form, as best shown in Fig.8, and the openings 5 are of the contour in cross-section shown in Fig. 11, and have an enlargement, 6, at theirlower extremity, over which we place the plate 7. The said passage or opening comes over feed conveyingtubes B, in which, in close proximity to the upper extremity thereof, as shown in Fig. 10, we place a screw, 8, which serves, in connection with the plate 7, to compel the rivets to fall shank foremost into the feed conveyingtubes B.

It will be observed upon referring to Figs. 7 8, and 10 of the drawings that the plate 7 is placed over the enlargement 6 of the dischargeopenings in the hopper, and that the rivets as they are brushed into the openings pass under the plate into the enlargement and thence into the feed-tubes B. If the rivets enter the open- Fig. 16 is a trans ings shank uppermost the shank collides with the edge of the plate and the rivet falls either sidewise or shank foremost into the feed-tubes B. Should it'fall sidewise into the feed conveyingtubcs it strikes against the screw 8, which is placed near the upper extremity of the tubes B for this purpose, and the contact of the rivet wit-h the screw 8 turns it shank foremost, and in this position it passes through the tube to the exit. The screw 8 is beveled llatwise to a point, as best shown in the sec tional view Fig 10, and the collision of the rivet with the screw compels it to fallin the desired position-4. 0., shank foremostthus securing the desired result.

The frames 4, carrying the brushes 3 on the spindle 2, are provided with a solid wing upon one side, which takes the place of one brush and serves to'crowd the rivets to and fro, while the brushes serve to sweep them into the dis charge-passages.

The feed conveying tubes B are connected to the dischargepassages 5, as bestshown in Figs.

1, 2, 3, and 5, and at their lower extremity supportspp,connected to the support a, which is secured to the upright portion D of the bracket D.

O C, Figs. 1, 2, and 3, is the combined shoeholder and riveting-block, and the same is located under the spring discharge-valves I) on the main frame F of the machine, immediately in front of the bracket D.

The combined shoe-holder and rivetingblock 0 is constructed and arranged to support the shoe or arctic adj ustably underneath -the rivet-forcing punches, andis operated, by

mechanism hereinafter described, to raise the overshoe to the rivet-forcing punches and to head thesame; but the detail construction and arrangement of the parts of the combined shoeholder and riveting block form the subjectmatter of another application to Jacob J. Unbehend for United States Letters Patent, and marked B, of even date herewith. Hence it is not necessary to describe in this application such detail construction and arrangement; .but its operation in connection with our present invention will be presently explained.

D is the curved bracket, mounted on the main frame F, provided with a vertical extension, D, and thesame in connection with the vertical extension serves to support the feedhopper or receptacle and the feed conveying and distributing mechanism,together with the punches for forcing the rivets into'thc overshoes'and their actuating mechanism.

E is the treadle for actuating the various levers, which serve to operate the feed-and force the rivets into the arctics or overshoes.

F is the main frame upon which all of the mechanism is supported.

G is the lever which serves to operate the plunger carrying the punches 'forforcing the rivets into the shoes, and also thedevice in the feed hopper for feeding out the rivets. It aecomplishes this through the medium of the toggle-lever g, the lever G being pivoted at g in the lugs provided at the upper extremity of the upright D and pivoted to the toggle g, which is connected to the plungerJ, carrying the head J, upon which are mounted the punches c. The lever G is retracted to its normal position by means of the yoke or baleshaped spring N. (Best shown in the top plan view, Fig. 4.)

The brushes in the feed-receptacle A are actuated when the lever G is depressed by the shaft 2, being connected to the lever G through the medium of the slotted lever 9,provided with'a slot, 10, which is pinned to the lever 11., and

the lever n is pivoted at n to the lever K, which has a slot, k, in which the pinf, connected to the lever G, rides vertically as the lever G is depressed.

The lever K is pinned at It" to the bracket D, and as the lever G is depressed the lever K is oscillated on the pivot which in turn oscillates the levers 9 through the connection of the lever n with the lever K, and this movement oscillates the shaft 2, carrying with it the frame 4 and the dependent brushes.

The lever G is connected to the treadle E by means of the connection it and the slotted guide H. The combined holder and rivetingblock 0 C is operated to raise or lower by" means of the toggle levers I 2' i. The togglelevers t i are pivoted in the yoke I, which is best shown in the detached view Fig. 6. The yoke I is secured beneath the frame F, as best shown in Figs. 1 and 5, directly underneath the combined shoe-holder and riveting-block, and the toggle-levers 2" across the plunger I, which extends up into the riveting-block and serves to force up the riveting-block inthe riveting operation, which will be presently explained. I

The lcvenarin I of the toggle-lever sets loosely-in the slot h of theguide H, as best shown in Fig. 9. The said slot h is ot'sufii cient length to allow the lever G to be depressed to the right point when the rivet is forced into the arctic. When the lever-arm I collides with the upper end of the slot h said arm is carried down with it, straightening the toggles M and forcing up the plunger P,and with it the riveting-block C, by means of which the rivets are headed or clinched in the arctic or overshoe.

The slotted guide H secured to the t-readle E at h by the connection h", and the lever-arm I is retracted to its normal position by means of the spiral S, and the t-readle E is retracted to its normal position by means of the spiral S, and the combined riveting-block and shoeholder is retracted to-its normal position by means of the spiral 5, Figs. 2 and 3.

It will be observed that the front leg, L, of the machine is broken away for the purpose of illustrating the yoke. M

'ets to enter the discharge-valves I). jug-tubes B are provided immediately above Thelower or discharge ends of the feed 0011- veying-tubes B are arranged inthe are of a circle, and secured on the semicircular bracket-piece a, as best shown in Figs. 12 and 13, and

their exits come immediately over the spring discharge-valves b, there being a spring discharge-valve b for each tube, B, and the exit ends of the tubes are so arranged in relation to p one piece of spring metal and are bifurcated, the opening extending up far enough to permit the metal arms to spread or spring sufficiently apart to allow the discharge of the The spring discharge-valves b are made of 8'5 1)" upon one-side, as best shownin Fig. 12, and

the exit end of the feed conveying-tubes B discharge into the slot, thus allowing the riv The feedthe exit end I) with a cut-off valve and mechanism, (best shown in the enlarged detached views, Fig. 14,) in which 6 is the eccentric lever pivoted at c on the side of the feed-tube, and provided with the wing extensions *0, which takes in the bore of the tube, and a spring mounted on the pivot-screw e to retract the cut off after the eccentric end {2 has been depressed. The cut-oilmechanism is automatically operated to let out one rivet at a time into the spring discharge-valves b by means of the fingers (7, attached to the supporting-piece a, carried on the plunger head J of the plunger J, and the cut-off mechanism is timed by the travel of thepunchescc, which areattached to the head J of the plunger J, as best shown at Figs. 15 and 17.

The punches c c are cylindrical in form, and are located so as to enter the spring dischargevalves 1), and are of sufficient length to force the rivets through the discharge-valves and into the arctic or overshoe held on the riveting-block G. X \Vhen-the treadle E is depressed thetoggle levers g g are actuated by the lever-arm G to force downward the plunger J, carrying with it the head J and the punches 0 0 attached thereto. In this downward movement the support a, carrying the fingerscl, causes the fingers d to collide with the cut-off mechanism, opening the feed-tubes, and arivet, which has been fed shank foremost into the tubes from the hopper-receptacle, drops down into y rise above the slots 1), and the cutoffs e imthe discharge-valve, and this is accomplished mcdiately close the passage in B, leaving the rivets held in the spring discharge-valves ready to be inserted in the arctic by .the descending punehts when the treadle is again depressed.

In order to guide the rivet accurately in its downward passage from the spring dischargevalve,we provide the pivoted forked yoke 0, having the arms 0 0, which embrace two sides of the spring dischargevalves b, as best shown in Fig. 17, and the yoke O is provided with the arm 0', pivoted at 0, and having the eccentric or angularlemr 'v, as best shown in Fig. 20.

It will be observed that the angular lever 12 is substantially at right angles with the arm 0 of the pivoted yoke, and that it lies substantially 011 the line drawn through the pivot 0 thereof and in the path of the lower edge, e, of the head J of the plunger J when the same descends as the treadle E is depressed.

The object of pivoting the forked yoke O in the manner described, and providing the same with the angular lever 12, is to so arrange the pivoted yoke as to throw it out of engagement with the disehargevalve at the right instant to allow the passage of the rivet from by the lower edge, '0, of the plunger head J colliding in itsdescent with the lever 12 of the pivoted yoke O, which, owing to its relative position with the pivot o, throws the yoke 0 out of engagement with the spring dischargevalve I) instantly, and permits the discharge of the rivet from the spring discharge-valve, as stated.

It will be observed that theexit ends of the feed are arranged on the circumference of a circle described through the center of the rivetingblock as a center, and the object of soarranging and locating the discharge ends of the spring-valves and feed conveying tubes Bis to arrange and distribute the rivets circumferentially on the heel or toe portion of the sole of the arctic or like overshoe, it being borne in mind that the purpose of the invention is to provide an eflicient machine which will simultaneously insert all of the rivets which are necessary toinsert in the heel or toe of the arctic or overshoe in one operation. It will be apparent that the object can be accomplished by so arranging the mechanism as stated, since if, as illustrated in the example, it is desired to insert four rivets at once, the discharge ends are arranged circumferentially, as shown in Fig. 13, and the necessary fingers d d provided to actuate the cut-off valves 0 e, and a like number of punches being employed, it is obvious that the four rivets will be fed downward simultaneously in the spring discharge-valve, and from thence forced into the heel or toe of the arctic or overshoe supported on the combined holder and riveti'ngblock O in one and the same operation. e

If it is desired to insert but one rivet into an arctic or overshoe-as, for example, to rivet the stay of an arctic or overshoe-then but one feeding-tube B is necessary, and in this case a single set of the described mechanism can be employed, and at Fig. 19 we have illustrated the mechanism thus arranged.

There is but one cut-off mechanism and one spring discharge-valve, and in this form we preferably make the discharge-valve with an auxiliary spring, b Fig. 19, as it holds the rivet with suflieient firmness to direct the same into the stay of the arctic without becoming displaced in the operation.

We do not restrict ourselves to the exact construction and arrangement of the various parts of the mechanism which we have illus trated in this example of our invention, since the same may be changed at will without departing from the principle of our invention.

The operation of our improved riveting'ma chine will be readily understood from the foregoing and from a consideration of the drawings.

The hopper or feed-receptacle is filled with rivets and the treadleEis depressed afew times until the disch arge-valves b are filled with rivets, after which the feed is substantially coir tinuous.

If the series of feed conveying-tubes B are employed, as illustrated in our present exanr able arm O, which may be adjusted to any,

length of arctic or overshoe readily. The treadle E, being depressed, straightens the toggles g g, carrying downward the plunger J and the punches c,attached to the head J, and the fingers (I, attached to the support a, collide inlheir descent with the cut-off mechanism e, thereby opening the passage and allowing another set of rivets to fall into the spring discharge valves simultaneously with the pushing out of those already occupying the discharge-valves, or rather the rivets fallinto the discharge-valve. proper when the punches c are retracted out of the discharge-valves, and the mechanism is ready for another operation.

It will be understood that the punches force down and out of the discharge-valves the rivets already occupying the-valves, and when the guide H strikes the lever-arm I the riveting-block O, carrying the shoe and shoe-holder, is raised up, and the rivets which are forced through the heel of the arctic are clinched or headed by the collision of the punches and riveting-block with the rivet between thetwo, and that the said punches and riveting-block, form whatwe term herein the heading mechanism of the machine.

The riveting-block C may carry any suitable IIO Having thus fully described our invention,
